NullPointerException in BaseEarlyStoppingTrainer when InvalidScoreIterationTerminationCondition used and first score is NaN #10190
Description
when I setup BaseEarlyStoppingTrainer to use InvalidScoreIterationTerminationCondition
if i get a NaN score at epochCount=0, then it throws a NullPointerException instead of just stopping
Exception in thread "main" java.lang.NullPointerException: Cannot invoke "org.deeplearning4j.nn.api.Model.score()" because "bestModel" is null
